基于非等覆盖半径的生鲜农产品配送中心选址

Location of distribution centers for fresh agricultural products based on non-equal coverage radius

研究非等覆盖半径思想下的生鲜农产品配送中心选址问题.结合生鲜农产品的时效性、响应性等特性,提出了一个基于非等覆盖半径的生鲜农产品配送中心选址优化模型.该模型能定量确定候选配送中心的可建区域、选址位置及配送方案.针对该模型是NP难问题,提出了一种基于自适应遗传算法的动态膜进化算法.最后,通过算例验证了模型和算法的有效性.

The location problem of distribution center （DC） for fresh agricultural products is considered under the thought of ＂non-equal coverage radius＂ in this paper. By integrating timeliness and responsiveness of the fresh agricultural products, a location model of DC based on the non-equal coverage radius is developed. The model can quantitatively determine the candidate region of DC, the site of opening DC and the quantity of product shipped from DC to customer. Since the model is a NP-hard problem, a dynamic membrane evolution- ary algorithm （DMEA） based on adaptive genetic algorithm （AGA） is proposed to solve the model. Finally, the results of an example demonstrate the validity of the model and algorithm.
